How do I change more than one property?

Currently, I have four items in my model and I want to turn off the visibility (if it is enabled) of the other three models. However, so far I have done this using three statements but I was wondering whether there is a quicker way to do this. Here is my code so far:

else
			step2.TextLabel.Text = "Step 2: Choose a drink:"
			step2.Visible = true
			step2.Main.Visible = false
			step2.Sides.Visible = false
			step2.Dessert.Visible = false
			step2.Drink.Visible = true

Is there a more efficient way of doing this?

You can usually replace repetitive code with a simple loop.

We will use the Instance:GetChildren() method to get the children inside of step2.

local step2Children = step2:GetChildren()

Then we can create a for loop to go over each child in the resulting table

local step2Children = step2:GetChildren()
for i,v in pairs(step2Children) do
	
end

In the for loop above, i is the index and v is the value. The index isn't important to us right now, so we will focus on v, which will represent each child of step2. We just need to set Visible to false for v.

local step2Children = step2:GetChildren()
for i,v in pairs(step2Children) do
	v.Visible = false
end

Now there could be a problem. If you have something in there that isn't a GuiObject, it will cause an error. This isn't a huge deal but it's better to handle it than to leave it. We just have to check if v is a GuiObject before setting Visible to false.

local step2Children = step2:GetChildren()
for i,v in pairs(step2Children) do
	if v:IsA("GuiObject") then
		v.Visible = false
	end
end

And if you want to make it a bit neater, you can remove the first line and merge it with the second.

for i,v in pairs(step2:GetChildren()) do
	if v:IsA("GuiObject") then
		v.Visible = false
	end
end

Hopefully this helps!
